India and Pakistan do limited trade by train and trucks through the Attari-Wagah land route border, 30 km from here.

Heroin and other drugs have been seized by customs and other agencies from cement bags earlier also. India has been importing Pakistani cement for over two years now.

Various agencies, like Border Security Force (BSF), Directorate of Revenue Intelligence (DRI), Punjab police and customs, have been keeping a strict vigil along the India-Pakistan international border to curb drugs smuggling.

This year, the BSF alone has recovered over 210 kg of heroin along the international border.
